Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 2-5, 8-9, 12, 15-16, 18-21 are is/are rejected under 35 U.S.C. 103 as being unpatentable over Palenske (US 2006/0053695). Re claim 2, Palenske discloses the fenestration system of claim 1, but fails to disclose wherein the first angled surface is configured to engage the first edge projection upon movement of the sill in the first direction a distance of 0.1 to 0.3 inches. However, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fenestration system of Palenske wherein the first angled surface is configured to engage the first edge projection upon movement of the sill in the first direction a distance of 0.1 to 0.3 inches in order to provide sufficient flexure of 106 such that 106 bends .1-.3 inches allowing for insertion of 102 on both sides. It has been held that a change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955). In addition, where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation. In re Aller, 220 F.2d 454, 456. Re claim 3, Palenske discloses the fenestration system of claim 1, but fails to disclose wherein the first angled surface is configured to engage the first edge projection upon movement of the sill in the first direction a distance of 0.175 inches. However, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fenestration system of Palenske wherein the first angled surface is configured to engage the first edge projection upon movement of the sill in the first direction a distance of 0.175 inches in order to provide sufficient flexure of 106 such that 106 bends 0.175 inches allowing for insertion of 102 on both sides. It has been held that a change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955). Re claim 4, Palenske discloses the fenestration system of claim 1, but fails to disclose wherein the second angled surface is configured to engage the second edge projection upon movement of the sill in the second direction a distance of 0.1 to 0.3 inches. However, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fenestration system of Palenske wherein the second angled surface is configured to engage the second edge projection upon movement of the sill in the second direction a distance of 0.1 to 0.3 inches in order to provide sufficient flexure of 106 such that 106 bends .1-.3 inches allowing for insertion of 102 on both sides. It has been held that a change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955). In addition, where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation. In re Aller, 220 F.2d 454, 456. Re claim 5, Palenske discloses the fenestration system of claim 1, but fails to disclose wherein the second angled surface is configured to engage the second edge projection upon movement of the sill in the second direction a distance of 0.175 inches. However, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fenestration system of Palenske wherein the second angled surface is configured to engage the second edge projection upon movement of the sill in the second direction a distance of 0.175 inches in order to provide sufficient flexure of 106 such that 106 bends 0.175 inches allowing for insertion of 102 on both sides. It has been held that a change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955). Re claim 8, Palenske discloses the fenestration system of claim 1, wherein a top (top of 102) of the first angled surface (left surface of 102) is wider than (Fig. 6, due to the notch proximate 108) a bottom (bottom of 102) of the first angled surface (left surface of 102), but fails to disclose wherein the first angled surface is angled from 35 to 55 degrees with respect to a bottom surface of the sill. However, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fenestration system of Palenske wherein the second angled surface is angled from 35 to 55 degrees with respect a bottom surface of the sill in order to allow the sill to easily slide over the sill cleat during assembly. It has been held that a change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955). Re claim 9, Palenske discloses the fenestration system of claim 1, but fails to disclose wherein the second angled surface is angled from 35 to 55 degrees with respect to a bottom surface of the sill. However, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fenestration system of Palenske wherein the second angled surface is angled from 35 to 55 degrees with respect to a bottom surface of the sill in order to allow the sill to easily slide over the sill cleat during assembly. It has been held that a change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955). Re claim 12, Palenske discloses the fenestration system of claim 1, but fails to disclose wherein the sill cleat has a profile height of about 3/8 inches or less. However, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fenestration system of Palenske wherein the sill cleat has a profile height of about 3/8 inches or less in order to ensure that sill cleat is not so tall as to prevent a larger tripping hazard, and to use as little material as possible to save costs. It has been held that a change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955). Re claim 15, Palenske discloses the fenestration system of claim 1, but fails to disclose wherein the sill cleat is formed of aluminum. However, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fenestration system Palenske wherein the sill cleat is formed of aluminum in order to utilize an inexpensive, durable, weather/water resistant and easily formable material. In addition, it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. See also Ballas Liquidating Co. v. Allied industries of Kansas, Inc. (DC Kans) 205 USPQ 331. Re claim 16, Palenske discloses the fenestration system of claim 1, but fails to disclose wherein the sill cleat is at least 10 inches long. However, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fenestration system of Palenske wherein the sill cleat is at least 10 inches long in order to span a significant length of the sill of the door for a better connection thereto. It has been held that a change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955). Re claim 18, Palenske discloses the fenestration system of claim 1, but fails to disclose wherein the sill cleat is divided into a plurality of discrete pieces. However, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fenestration system of Palenske wherein the sill cleat is divided into a plurality of discrete pieces in order to shorten the overall length allowing for smaller parcels for shipping and/or transportation. It has been held that making seperable is within the level of ordinary skill. In re Dulberg, 289 F.2d 522. Re claim 19, Palenske discloses the fenestration system of claim 1, but fails to disclose wherein the sill cleat has a substantially rectangular perimeter. However, it would have been obvious as a matter of choice to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fenestration system of Palenske wherein the sill cleat has a substantially rectangular perimeter in order to simplify manufacture by eliminating a need for angled, inclined, and/or notched surfaces. In addition, it has been held that a mere change in shape of a component is within the level of ordinary skill in the art absent persuasive evidence that a particular configuration of the claimed shape is significant. In re Dailey, 357 F.2d 669, 149. Re claim 20, Palenske discloses the fenestration system of claim 1, but fails to disclose wherein the sill cleat has a substantially circular perimeter. However, it would have been obvious as a matter of choice to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fenestration system of Palenske wherein the sill cleat has a substantially circular perimeter in order to reduce the footprint of the sill cleat and thus material used, as a circular perimeter would utilize a smaller area than that of the rectangle presented. In addition, it has been held that a mere change in shape of a component is within the level of ordinary skill in the art absent persuasive evidence that a particular configuration of the claimed shape is significant. In re Dailey, 357 F.2d 669, 149. Re claim 21, Palenske discloses the fenestration system of claim 1, but fails to disclose wherein the sill cleat has a curvilinear perimeter. However, it would have been obvious as a matter of choice to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fenestration system of Palenske wherein the sill cleat has a curvilinear perimeter in order to reduce the footprint of the sill cleat and thus material used, as a curvilinear perimeter would utilize a smaller area than that of the rectangle presented. In addition, it has been held that a mere change in shape of a component is within the level of ordinary skill in the art absent persuasive evidence that a particular configuration of the claimed shape is significant. In re Dailey, 357 F.2d 669, 149. Claim(s) 6 are is/are rejected under 35 U.S.C. 103 as being unpatentable over Palenske (US 2006/0053695) in view of Salvoni (US 2023/0009152). Re claim 6, Palenske discloses the fenestration system of claim 1, but fails to disclose further comprising a polymeric composition, wherein the polymeric composition is disposed adjacent to the first angled surface and the second angled surface. However, Salvoni discloses further comprising a polymeric composition ([0056]; silicone), wherein the polymeric composition ([0056]) is disposed adjacent to the first angled surface (38 on the left) and the second angled surface (38 on the right). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fenestration system of Palenske further comprising a polymeric composition, wherein the polymeric composition is disposed adjacent to the first angled surface and the second angled surface as disclosed by Salvoni in order to secure the angled surfaces to the edge projections ([0056]) and to utilize a cheap, readily available, easily formable material. Claim(s) 17 are is/are rejected under 35 U.S.C. 103 as being unpatentable over Palenske (US 2006/0053695) in view of Smith (US 5,283,977). Re claim 17, Palenske discloses the fenestration system of claim 1, but fails to disclose wherein a bottom surface of the sill cleat defines one or more feet. However, Smith discloses wherein a bottom surface (bottom of 16) of the sill cleat (16) defines one or more feet (42, 44, 46). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fenestration system of Palenske wherein a bottom surface of the sill cleat defines one or more feet by Smith in order to elevate the sill cleat for ventilation or the passage of water.
